The Youngs say there will obviously be no hanky panky when they’re atop Fellowship Church, but after that, they’ll join fellow members in a weeklong effort to use sex to strengthen marriages in a spiritually healthy way.

“Sex is bigger than most people imagine, more multifaceted than people think of and most couples don’t think deeply enough about sex,” said Lisa Young. “Sex is not just a physical thing. It’s a spiritual, emotional thing… that God created.”

Ed and Lisa Young recently published a book with the results of their first “sexperiment” and offered suggestions for how the church can facilitate appropriate conversations about sex, despite age-old taboos on the subject.

“God said we are meant to make love within the beauty and covenant of marriage,” Ed Young said. “The role of sex in a Christian marriage is the superglue that holds it together.”

If Young looks familiar, that’s because his father—also named Ed Young—is pastor of Second Baptist Church in Houston, the largest Southern Baptist congregation in the country.
